Objectif Machines used underground are becoming more and more powerful, but at the same time generate more and more dust.Spraying systems have been developed, providing a very fine spray to combat this dust.Such high-tech systems are sensitive and little used, as the available water contains solid or flocculates which tend to block or even damamge them, particularly as a result of abrasion.The aim of the research is to develop methods and products capable of eliminating pollutants and thus improving water quality.The different analyses of the water used in H.B.L. mines have shown that the waters used to control dust are aggressive and able to clog spray's nozzles. This is related to their high content of iron and calcium bicarbonate.In order to avoid this clogging phenomena, a dispersion treatment is necessary.The definiton and the operational use of such a treatment should improve working conditons in the faces by reducing the dust content in the atmosphere.It should, on top of that, save natural resources by reducing the industrial use of drinking-water in the mines.The project comprises several phases:- Analysis of water used underground,- Development of methods and products to eliminate pollution, in conjunction with specialized firms and laboratories,- Adaptation of these methods and products for use underground,- Undrground tests and final development.The programme comprises the development and implementation of products and/or methods aimed at purifying the industiral water used underground by removing suspended solids and preventing the flocculation of substnaces in solution.The research will be conducted in conjunction with firms and laboratories which specialize in this type of treatment, in order to study their products and/or methods and establish whether or not these are suitable for use underground, taking account of technical feasibility, regulations and economy.The research is expected to lead to the design of new treatment methods and installations and the specification of products for mines.
